Application filed May 15,

To @ZZ whom it muy concern:

Be it known that l, VILLIAM E. FowLEi-i, Jr., residing at Mount Lebanon, in the county ot Allegheny and State otr Pennsylvania.,

-a citiren ot the vUnited States, haveinvented or discovered certain new and uset'ul lmprovements in Securing Brake-Beam `Supports to Trucks, of'` which improvements the following is a4 specification. v

The invention described herein relates to certain improvements in the manner of securing the supporting rails trom brake beams to trucks, described and claimed in an application filed May 15, 1924, Serial No. 713561, said improvements' being hereinafter more fully described and claimed.

In the accompanying drawings forming a part of this speciiication F ig. l is a vien7 part-ly in section and partly in elevation illustrating the improvement claimed herein; is a sectional plan view on a plane indicated by the line IIE-1l, Fig. 1;

Fig. 3 is a transverse section on a plane indica-ted by the line III-III, Fig. 2; Figs. 4 and 5 are views similar respectively to Figs. 1 and 2, illustrating a modilication ot the improvement.

Generioally stated, the invention describedand claimed in the above application consists in so attaching the supporting rail to an element of the truck that it will have a resilient bearing at three spaced points on the truck element; e.v the spring plank two Ot such points of bearing being on one side, e. g. the underside of the spring plank, while the third point ot bearing which is intermediate the Others, is on they upper side of the spring plank. The specific embodiment ot the improvement consists in so forming the rail that the intermediate point of bearing of the rail on the truck element is formed by a. loop or U- shaped portion adapted to project through an opening in the truck element, the rail being held in position by a key passingthrough the loop and bearing on the truck element.

In the embodiment of the invention described and claimed herein the supporting rail is constructed substantially similar to the construction of the railfin the above application and is provided with inclined portions 3 on which are movably mounted blocks or shoes 4 provided withv means for 1924. Serial No. 713,562.

plank. These portions 8 which are resilient,

are. -made integral with a projection 7 adapted to be passed through an Opening in the spring plank. As clearly shown in Fig. 2, this opening is made ot a key-hole shape having the larger portion 9 of sutlicient dimensions to permit of the passage Ofa head 11 on the projection 7 and a portion 9 having a width substantially less than theY Width of the head. The large opening is located at one side of the position which the rail is to occupy and the smallerportion 91% in line with such position. In attaching the rail to the spring plank, the spring portions Saro pressed upwardly until the head 1l passes through the opening when the inner rail is moved laterally moving the part 7 of the projection into the narrow opening and the head overlapping the edges of this narrow Opening, as shown in Fig. l. In order to prevent a lateral movement of the rail, a block l2 is placed in the larger openins, 13 overlapping the edges of the larger opening and is kheld in position by a key 14 passing through the lower end of the block and bearing against the underside of the spring plank. There the spring plank is formed by two spaced angle bars, as'shown in Figs. 4 and 5, a plate 15 is so secured by riveting or otherwise to the angle bars as to bridge the spaces between them, and the key-hole opening is formed in this spring plank, 'as shown in Figs. 4 and 5.

I claim herein as my invention:

1. The combination of a truck element having a key-hole shaped opening therethrough and a supporting rail provided intermediate its ends with a projection having a head or enlargement at its end adapt-ed to bear on the element at the sides of the narrower portion of the opening through said element 2. rll'he combination of a truck element having a key-hole shaped opening therethrough and a supporting rail provided intermediate the ends with a projeetionhavsaid .block beinO' Jrovided with flanges ing a. head or enlargement at its end adapt-- ed to bear on the element at the sides of the narrower portion of the opening through said element, and means for preventing lateral movement of the rail from operative position.

3. The combination of a truck element having a key-hole shaped opening therethrough and a supporting rail having spaced points of bearing on one side of the truck element and provided intermediate said points ot hearing with a projection having a head or enlargement adapted to hear on the element at the sides of the narrower portion ot the opening through the element.

4. The combination or' a truck eiement having a key-hole shaped opening therethrough and a supporting rail having spaced points of hearing on one side of the 2 truck element and provided intermediate said points of hearing with a projection having a. head or enlargement adapted to hear on the element at the sides of the narrower portion of the opening through the element7 the portions intermediate the hearing portions and the projection being resilient.

5. The combination of a truck element having a key-hole shaped opening therethrough and a supporting rail provided intermediate its ends with a projection having a head or enlargement at its end adapted to bear on the element at the sides ol' the narrower portion of the opening through said element, and a block itting into the larger portion of the opening in the truel; element and adapted to prevent lateral movement of the rail.

In testimony whereof, I have hereunto Set my hand.
